Destined (5)
I believe the answer is:
fated
'destined' is the definition.
(someone fated to do something is destined to it)
This is the entire clue.
(Other definitions for fated that I've seen before include "Destined, foreordained (5)" , "Suffering a lot" , "Doomed or destined" , "Destined - inevitable" , "Predestined" .)
